The specific embodiment

Piezoelectric can produce voltage when deformed by the external force effect, designed the piezo-electric generating footwear of spontaneous impulsive force generating when utilizing the people to walk based on this principle.The people is in the process of walking, when pin lands, as shown in Figure 5, pedal 6 is subjected to downward active force, cushion 7 can guarantee that pin is comfortable, beaer 4 and force transfer body 5 are transformed into horizontal force action to this power on the piezo-electric crystal 3 on flute profile box 2 both sides, make it to produce faint distortion, and the electrode b of piezo-electric crystal 3 produces instant high-voltage; When less touch with the ground, as shown in Figure 6, the power that acts on the piezo-electric crystal 3 disappears, and the distortion of piezo-electric crystal 3 recovers, and the electrode c of piezo-electric crystal 3 produces instant high-voltage.The electrode of two piezo-electric crystals 3 is connected on the socket 10 of external output, and when the people walked, pin landed liftoff repeatedly, and power-generating shoe is by socket 10 outside outputs alternating current as shown in Figure 7.

The alternating current of piezoelectricity footwear output through rectification, filtering, voltage stabilizing, becomes voltage and releives relatively in electric storage device 12, to the rechargeable battery set charging, outwards exports electric energy for use by electric storage device 12.Electric storage device 12 can hang on the waistband or be placed in the pocket, and the time spent can not pulled up plug 11 at any time.Experiment records, and when the people of body weight 68kg normally walked, single power-generating shoe can the output open circuit crest voltage be 14.8 volts a alternating current.
